Olympus E-450 vs Pentax 645Z Sensor Comparison

Quite often, it is hard to visualise the difference in sensor measurements merely by viewing technical specs. The graphic here may provide you a more clear sense of the sensor sizes in the E-450 and 645Z.

As you have seen, both the cameras posses different resolutions and different sensor measurements. The E-450 with its smaller sensor will make achieving shallower depth of field more difficult and the Pentax 645Z will provide you with more detail using its extra 41MP. Greater resolution will also make it easier to crop pics somewhat more aggressively. The older E-450 will be disadvantaged in sensor innovation.
